25. Novas propriedades do SKTI (Inibidor de tripsina de soja): inibição para elastase neutrofílica humana e efeitos no processo de injúria pulmonar aguda
Seeds from legumes including the Glycine max are known to be a rich source of protease inhibitors. The soybean Kunitz trypsin inhibitor (SKTI) has been well characterised and has been found to exhibit many biological activities. However its effects on inflammatory diseases have not been studied to date. In this study, SKTI was purified from a commercial soy

26. Presença do genoma do herpesvírus bovino 5 e do herpesvírus bovino 1 no SNC de bovinos sadios, portadores de meningoencefalite herpética e outras encefalopatias
Os herpesvírus bovinos 1 (BoHV-1) e 5 (BoHV-5) são vírus de DNA de fita dupla, com envelope glicoprotéico, que pertencem à subfamília Alphaherpesvirinae, gênero Varicellovirus. A principal propriedade biológica dessa subfamília é a capacidade de estabelecer latência após a infecção aguda, quando não é possível sua detecção, exceto quando s

27. Emprego de estirpes de leptospiras isoladas no Brasil, na microtécnica de soroaglutinação microscópica aplicada ao diagnóstico da leptospirose em rebanhos bovinos de oito estados brasileiros / Use of strains of leptospires isolated in Brazil, for the microscopic agglutination test applied to the diagnosis of leptospirosis in bovine herds of eight Brazilian states
Bovine leptospirosis is one of the main reproductive diseases which interferes economically on the livestock and thus it is needed the amelioration of the laboratory diagnostic procedures. The aim of this work is to investigate the adequacy to use autochthonous strains of leptospires isolated in Brazil, added into the antigen collection applied for the micro

28. Análise morfométrica 2D e 3D de amostras de osso trabecular utilizando microtomografia tridimensional por raio-X / 2D and 3D morphometric analysis of trabecular bone using X-ray tridimensional microtomography (müCT)
Trebecular bones have a porous microstructure and can be modeled as a linear elastic solid, heterogenous and anisotropic. The x-ray tridimensional microtomography (müCT) has been worldwide used for the assessment of trabecular bone in investigations related to bone quality and aimed to the diagnostic of bone metabolic diseases such as osteoporosis. In the l

29. HISTOLOGIC EVALUATION OF LUNG IN THE NELLORE BOVINE FINISHED UNDER GRASING CONDITIONS AND IN FEEDLOTS / AVALIAÇÃO HISTOLOGICA DE PULMÃO DE BOVINOS DA RAÇA NELORE TERMINADOS A PASTO E EM CONFINAMENTO.
Most Brazilian states have common features, as the problems that affect the health of animals. Infectious and contagious diseases, parasites, and metabolic deficiencies, are of great importance, directly interfering in economic indicators. Respiratory diseases have highlighted the various systems of breeding cattle, because they have lung particular characte

31. Congenital hidranencephaly and cerebellar hypoplasia in water buffaloes / Hidranencefalia e hipoplasia cerebelar congênita em búfalos Murrah
Hereditary hydrancephaly and cerebellar hypolasia are reported in Murrah buffalos. Six calves, one female and 5 male out of 128 born between 2004 and 2008 in a farm in southern Brazil were affected. All affected calves were offspring from the same bull. No affected buffaloes were observed in the descendants of other three bulls used in the farm. Main clinica

32. Determinantes econômicos da sanidade bovina / Economic determinants of bovine health
The bovine livestock is one of the most important sectors of Brazilian agribusiness. However, Brazilian herds health - key to the activity is still an issue rarely studied in economic terms. This way, the present study tried to identify the major determinants of the use of preventive measures and its expenses. Thus, the work was divided into two parts. At fi

33. Imunobiologia das infestações de bovinos pelo carrapato Rhipicephalus (Boophilus) microplus: estudo dos correlatos imunes de resistência e de susceptibilidade / The immunobiology of infestations with the cattle tick Rhipiceplahus (Boophilus) microplus: comparative immunologic and molecular studies of the tick-host interface in susceptible and resistant bovine hosts.
The skin of vertebrates is the largest for over 15,000 species of hematophagous arthropods. Among them are ticks, which are long-term feeders and interact with host defenses for days to weeks. Little is known about specialized strategies for eliminating ectoparasites, but ticks can induce immune responses in host. Bovines present variable and heritable level

34. AvaliaÃÃo da presenÃa de PapilomavÃrus bovino em sÃmen de touros (Bos taurus)
Papillomaviruses (PV) are viruses that contain double strand DNA and can infect the squamous epithellium of the skin and mucosa. There are 10 different types of BPV (BPV-1 to 10) and they can cause serious diseases in dairy herds or cutting, creating great economic losses to farmers in Brazil and other countries. The presence of BPV has been detected in repr

35. Mycoplasmosis in cattle dairy calves: underlying factors for the occurrence and manifestation of the syndrome granular vaginitis / Micoplasmose em bovinos de aptidão leiteira: fatores predisponentes para a ocorrência e manifestação da síndrome vulvovaginite granular
The reduction of reproductive rates is measured by the reduction in the number of calves born that immediately reflected in the reduction of milk production and profitability of commercial property. The effect is the increased administrative costs of maintenance with dry cows, higher rates of rejection and a higher number of doses of semen for conception. Pa

36. Identificação e estudo da diversidade do papilomavírus associado a lesões cutâneas em bovinos
Papillomaviruses (PV) has a worldwide distribution and is recognized as an etiologic agent associated with several benign and malignant epithelia lesions in human and animals. The Papillomaviridae family is a highly heterogeneous group of viruses, which has 18 genera, and likely occurs in most mammals and birds. The PV genome is circular double-stranded DNA
